How far are you, xtc wise?
Do you get the xtc logo when you load your daw?
Can you run plugins in xtc mode?

It's working fine here.. Not at the scope pc so I can't post screenshot though.
Open up your xtcproject file located in scope/app/xtc ( I think that's the folder order... Otherwise there is a folder called xtc with an xtcproject.pro file somewhere:)

Open that in scope and open your daw. Edit the project until you have made all the connections you need (Adat etc) and save. Close scope and open your daw.

change the number of asio ins/outs by clicking the asio boxes. THey should have 8 in/out.

Then connect the asio sources to adat dest, and adat source to asio dest.

you can disconnect the "merger" module for now and just leave it somewhere in the project window, unconnected. the same goes for the directMixerPlayer. well talk about them later.

Then fire up your daw (reaper cubase, pro tools etc) while scope is still running.
Do you have sound?
if yes, save the project and close your daw, then after that scope, and then load up your daw again.
